Given numbers are 643,556,627,19

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 643,556,627,19 is 224157516.

Find LCM of 643,556,627,19 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

19 x 643 x 556 x 33 x 1 = 224157516

Therefore, the lowest common multiple of 643,556,627,19 is 224157516.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

643 x 556 x 627 x 19 = 4258992804

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

643 : 1, 643

556 : 1, 2, 4, 139, 278, 556

627 : 1, 3, 11, 19, 33, 57, 209, 627

19 : 1, 19

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,556,627,19, is 1.

Now, the common factors can be found like this.

643:643

556:2x 2x 139

627:3x 11x 19

19:19

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

19 = 19

Therefore, the value for common factors is 19.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 4258992804/(1x19)

LCM = 4258992804/19

LCM = 224157516

Thus, we can understand that the LCM of 643,556,627,19 is 224157516.
